Heat require to boil 15.6 g iron from 122 C0to 355 C0 whereas,
Where, m is mass of iron
s is specific heat of iron
d T is change in temperature in celcius
If
1 cal = 4.2 J
Then,
Thus 0.389 k cal of enrgy is required by a 15.6 g Fe to reach to 355 C^0
<u>Answer:</u>
<em>D. The reverse reaction rate increases.</em>
<u>Explanation:</u>
The<em> rate of reverse</em> increases if the products are increased in a mixture at equilibrium.
At first,<em> rate of forward and backward</em> reactions are same for a <em>mixture in equilibrium.
</em>
<em>If we add products or,the reaction moves to the opposite side I.e towards reactants side.</em>
so,according to the Le Chateliers principle,the reaction shifts opposite to the side of increase. so,according to the Le Chateliers priciple, <em>the rate of reverse or backward reaction will increase with the increase in the products.</em>
